The range has been a top concern for potential buyers transitioning from internal combustion vehicles to electric ones. In 2008, when EVs were still a rare new concept, Tesla promised a 200-mile (320 km) range on a single charge on its Roadster, a model it soon discontinued. Its second offering, Model S, promised a higher range of 249 miles (401 km) in 2012.
RMIT University’s new proton battery could revolutionize energy storage, offering a safe, affordable, eco-friendly alternative to lithium-ion batteries.
The latest ‘proton battery’ developed by RMIT University holds the potential to revolutionize power supply for homes, vehicles, and devices without the disposal-related environmental challenges posed by lithium-ion batteries.
The battery works by using a carbon electrode to store hydrogen that has been separated from water, functioning like a hydrogen fuel cell to generate electricity.
The technology can also be used in fog and smoke, aiding firefighters.
This is according to a report by PopSci published on Wednesday.
Researchers at Purdue University and Los Alamos National Laboratory have joined forces to engineer something they call “heat-assisted detection and ranging,” or HADAR, which consists of a completely new camera imaging system based on AI interpretations of heat signatures. The technology could soon allow vehicles and robots to see at night time.
A once muddy, unclear tech
We have all seen movies where agents use thermal imaging to see their surroundings in the dark, but in reality, this technology is far from practical because thermal radiation particles diffuse into their nearby environments. This means that trying to image them becomes a complicated, muddy, and unclear process.
Organic light-emitting diodes (OLEDs) are now widely used. For use in displays, blue OLEDs are additionally required to supplement the primary colors red and green. Especially in blue OLEDs, impurities give rise to strong electrical losses, which could be partly circumvented by using highly complex and expensive device layouts. A team from the Max Planck Institute for Polymer Research has now developed a new material concept that potentially allows efficient blue OLEDs with a strongly simplified structure.
From televisions to smartphones: organic light-emitting diodes (OLEDs) are nowadays finding their way into many devices that we use every day. To display an image, they are needed in the three primary colors red, green and blue. In particular, light-emitting diodes for blue light are still difficult to manufacture because blue light—physically spoken—has a high energy, which makes the development of materials difficult.
Especially the presence of minute quantities of impurities in the material that cannot be removed plays a decisive role in the performance of these materials. These impurities— oxygen molecules, for example—form obstacles for electrons to move inside the diode and participate in the light-generation process. When an electron is captured by such an obstacle, its energy is not converted into light but into heat. This problem, known as “charge trapping”, occurs primarily in blue OLEDs and significantly reduces their efficiency.
According to a person with direct knowledge of the matter, representatives from Tesla are planning to meet India’s commerce minister this month to discuss the possibility of constructing a factory for producing an all-new $24,000 electric car. Tesla has expressed interest in manufacturing low-cost electric vehicles for both the local Indian market and exports. This meeting would mark the most significant discussions between Tesla and the Indian government since Elon Musk’s meeting with Prime Minister Narendra Modi in June, where he expressed his intention to make a substantial investment in the country.
There are now over 1.9 million orders for the long-awaited Tesla Cybertruck, per a crowd-sourced data tracker. Speaking on an Earnings Call earlier this week, Tesla CEO Elon Musk stated that demand for the Cybertruck is “so off the hook, you can’t even see the hook.”
Given that Tesla plans to produce 375,000 Cybertrucks a year at peak capacity, new orders will technically take around 5 years to arrive. That said, a significant amount of reservation holders may not follow through with their purchase — after all, the deposit to reserve a Cybertruck was only $100. The Cybertruck is being produced at Giga Texas, although it’s a possibility it could also be built at Giga Mexico when the proposed factory is up and running in a few years’ time.
It will be interesting to see if the Cybertruck will be offered outside of North America. Currently, those in Tesla’s European and Asian markets can pre-order the truck. That said, the Cybertruck’s large size and hefty weight could make selling it overseas a serious challenge. For example, in several European nations it would have to be classed as a commercial truck or semi.
With US car thefts up 25.1% since 2019, it’s clear that high-tech key fob immobilizers aren’t cutting the mustard. But this might: UMich researchers have created a charmingly low-tech anti-theft device that turns the whole car into a security keypad.
Keyless entry and ignition are a brilliant step up in convenience from the old “stick key in hole and turn” method of starting cars, but thieves and hackers with a bit of know-how and some specialist gear are finding late-model keyless cars quick and easy to break into and steal. Between this kind of thing and Tik Tok car theft challenges, criminals are having a field day in the post-COVID era.
A team at the University of Michigan has come up with a fun solution that doesn’t use wireless signals at all. The “Battery Sleuth,” as they’ve called it, sits between the car’s battery and its electrical system, and measures fluctuations in voltage, looking for a specific set of voltage changes that act as a secret handshake of sorts between driver and car. Only when this handshake is complete will the device let the full power of the battery through to fire up the starter motor.

During a press conference held yesterday in Seoul, South Korea, Hyundai Motor Group revealed plans for a new generation of high-tech cars incorporating nanoscale features, which it hopes to begin mass producing by 2025–2026.
Nanotechnology is defined as materials or devices that work on a scale smaller than one hundred nanometres (nm). A nanometre is one billionth of a metre or about 100,000 times narrower than a human hair. Individual atoms, for comparison, tend to range in size from 0.1 to 0.5 nm. Many interesting and unique physical effects become possible at this level of detail, making nanotechnology a highly promising technology of the future.
Built using inexpensive semiconductors, the device packs all components to make hydrogen and can be scaled.
A research team led by Aditya Mohite, a professor of chemical and biomolecular engineering at Rice University in the US, has designed a device that can use sunlight to generate hydrogen, with a record efficiency of 20.8 percent, a press release said.
Hydrogen is being touted as the future of clean energy due to its high energy density that could be deployed even to fly large planes. However, the process of generating hydrogen is currently heavily dependent on fossil fuels. For hydrogen to herald a new future in clean energy, it needs to be produced sustainably and without carbon emissions.
